RESUMO:

Brazil ranks second in the broiler production ranking, generating income for thousands of those involved in the production. Poultry mortality losses generate an economic impact of around a hundred million of dolars for each percentage point of mortality. The use of genetics directed to zootechnical performance and carcass yield brought huge advances in product development, genetic and zootechnical performance and some side effects including the presence of locomotor problems, which means increased mortality rates by sacrifice. Among the locomotor problems of broilers, there are in the literature several syndromes of genetic / metabolic origin, as well as infectious conditions. By analyzing the data from 100 broiler flocks records totaling 2.63 million birds housed in a real production system under field variations, the present work aimed to study the occurrence of locomotor problems in order to reduce the impact on mortality by elimination and the impact on animal welfare through a statistical model. Mortality due to locomotor problems was directly correlated with the end-of-flock mortality rate of 58% and litter quality in 19%. The distribution of occurrences was higher in the first week and in the pre-slaughter week. The GAIT SCORE empirical method described by the University of Bristol did not prove to be an efficient model, possibly due to the variability of understanding on evaluation application.
